7 Purpose:
8 	Execute stereo command.
9 
10 Input:
11 	(1) Pointer to MolComplexS structure.
12 	(2) The number of macromolecular complexes.
13 	(3) Pointer to RuntimeS structure.
14 	(4) Pointer to ConfigS structure.
15 	(5) Pointer to GUIS structure.
16 	(6) Pointer to NearestAtomS structure.
17 	(7) The number of pixels in the main window free area.
18 	(8) Pointer to refreshI.
19 	(9) Pointer to  the remainder of  the command string.  It is  either
20 	    empty or contains the keyword OFF.
21 
22 Output:
23 	(1) Stereo flag set.
